ABSTRACT

BACKGROUND: Oral hairy leukoplakia (OHL) is an EBV-associated condition of the oral mucosa, which is often painless. It is found predominantly in HIV-positive patients and is considered a clinical indicator of immunosuppression. OHL has rarely been described in HIV-negative patients, being found most often in association with iatrogenic immunosuppression. OHL induced by topical steroids remains extremely rare. PATIENTS AND METHODS: An 81-year-old HIV-negative woman, treated for 3 months with topical steroids for oral lichen planus, developed an asymptomatic white, corrugated, non-removable plaque with vertical folds on the lateral edge of the tongue. Associated oral candidiasis was noted. Based upon histological findings and in situ hybridisation showing numerous EBV-infected epithelial cells, a diagnosis of oral hairy leucoplakia was made. DISCUSSION AND CONCLUSION: To our knowledge, we report herein only the second recorded case of OHL induced strictly by topical steroids. Self-medication and poor adherence to dosage recommendations were noted in the patient's medical history. Physicians must be aware of the rare but nevertheless possible adverse events associated with topical steroid use, particularly when such medication is prescribed over a long period for inflammatory diseases of the oral mucosa.

ABSTRACT

A 26-year-old Australian female traveller in Sierra Leone presented with an irritant bullous contact dermatitis consistent with paederus dermatitis. The lesions were treated with a potent topical corticosteroid with good effect. The affected area resolved in 6 weeks and hyperpigmention persisted for months until complete resolution. This dermatitis occurs when beetles of the genus Paederus (rove beetles) are crushed on the skin, releasing pederin. The same dermatitis ensues with Australian Paederus species. Serial clinical photographs are presented which will aid Australian dermatologists in the diagnosis of this dermatitis, which presents in regional Australian patients and returned overseas travellers.

ABSTRACT

Alopecia areata (AA) is a non-scarring tissue-specific autoimmune disorder. Many therapeutic modalities are available for the treatment of AA, but none has yet proven to be uniformly effective. Fractional carbon dioxide (FRCO2) laser has been introduced as a treatment modality for AA. The objective is to evaluate and compare the efficacy and safety of FRCO2 laser in treatment of AA alone or in combination with betamethasone valerate cream. 30 patients were assigned to one of the following groups, Group A FRCO2, Group B FRCO2 plus betamethasone valerate cream or Group C (betamethasone valerate cream). Patients received eight laser sessions 2 weeks apart, treatment period was 4 months. A statistically significant decrease in SALT score, dystrophic hair and a statistically significant increase in terminal hair was observed in all groups. Patient satisfaction level and reduction in SALT score were significantly higher among FRCO2 and FRCO2 plus betamethasone valerate group. However, no statistical significant difference was found between FRCO2 group and FRCO2 combined with betamethasone valerate cream group. FRCO2 laser is a safe and effective treatment modality for AA when used alone or in combination with betamethasone valerate cream. However, it was found superior to betamethasone valerate cream monotherapy.

ABSTRACT

A 51-year-old man presented with a 12-year history of an expanding, irritable rash on his buttocks, groin and scrotum. He gradually developed erythematous, annular plaques with ridged borders and depressed centres. He also had a verruciform eruption in his perianal area. A clinical diagnosis of porokeratosis confined to the genitogluteal area was confirmed histopathologically. Oral acitretin resulted in symptomatic and cosmetic improvement. He continues to be followed up to evaluate treatment outcomes.

ABSTRACT

INTRODUCTION: This is a randomised, multi-centre, open-label, phase II study to evaluate the efficacy of betamethasone valerate ointment on radiation-induced oral mucositis in patients with head and neck cancer undergoing concomitant radiotherapy with cisplatin or cetuximab. METHODS AND ANALYSIS: The trial will take place at seven hospitals in Japan. Patients will be randomised (1:1) into betamethasone and control groups after the occurrence of grade 1 oral mucositis. In the betamethasone group, patients will use betamethasone valerate ointment five times a day, in addition to usual oral hygiene guidance. The primary endpoint is the incidence and onset time of grade 3 oral mucositis. The secondary endpoints are the incidence and onset time of grade 2 oral mucositis, incidence and onset time of oral candidiasis, completion of radiation therapy and adverse events. Target accrual is 102 patients with a two-sided type I error rate of 5% and 80% power to detect an 80% risk reduction in the incidence of grade 3 oral mucositis. ETHICS AND DISSEMINATION: This study was approved by the Clinical Research Review Board of Nagasaki University (No. CRB20-009). All participants will be required to provide written informed consent. Findings will be disseminated through scientific and professional conferences and peer-reviewed journal publication. The datasets generated during the study will be available from the corresponding author on reasonable request. TRIAL REGISTRATION NUMBER: jRCTs071200013.

ABSTRACT

BACKGROUND: Topical pimecrolimus may maintain remissions of atopic dermatitis (AD) by inhibiting subclinical inflammation. OBJECTIVE: To evaluate clinical and cytological effects of pimecrolimus in topical corticosteroid-treated and resolved AD lesions. METHODS: Patients (n=67) with resolved AD lesions were randomized to 3-week double-blind treatment with either pimecrolimus cream 1% or vehicle cream. Outcome measures were reduction in Eczema Area and Severity Index (EASI) and number of leukocytes in skin biopsies in all randomized patients who were evaluable at the end of study. RESULTS: The proportion of patients with a localized EASI<2 at the end of study was higher with pimecrolimus cream 1% than with vehicle cream (73.5 vs. 39.4%, respectively). There was a significant decrease in the number of infiltrating CD45+ cells in pimecrolimus cream 1% compared with placebo cream (-88.2 vs. 43.2 cells/mm(2), respectively, p=0.047) and a slight but nonsignificant reduction in the number of dermal dendritic cells, Langerhans cells, T cells and macrophages with pimecrolimus versus vehicle cream. LIMITATIONS: This was an exploratory study. CONCLUSION: Topical pimecrolimus was effective at maintaining betamethasone-17α-valerate-induced AD remission by inhibiting recurrences of the inflammatory infiltrate in the skin.

ABSTRACT

BACKGROUND: Atopic dermatitis (AD) affects health and quality of life and it has great impact on both health-care costs and costs to the society. OBJECTIVES: The objective of this study was to develop a model to analyse the cost-effectiveness of a barrier-strengthening moisturizing cream as maintenance therapy compared with no treatment after initial treatment with betamethasone valerate in adult patients with AD in Sweden. A further aim was to apply a similar health-economic analysis for Denmark, Norway and Finland. METHODS: A Markov simulation model was developed including data from three sources: (i) efficacy data from a randomized controlled trial including patients with moderate AD treated with either a moisturizing cream or no treatment, (ii) resource utilization and quality of life data, and (iii) unit prices from official price lists. A societal perspective was used and the analysis was performed according to treatment practice in Sweden. The model simulation was also applied for Denmark, Norway and Finland with inclusion of country-specific unit costs. Sensitivity analyses were performed to test the robustness of the results. RESULTS: The results from the present analyses of treatment for patients with moderate AD indicate that maintenance treatment with a moisturizing cream during eczema-free periods could be cost-effective in a societal perspective. Similar results were obtained for Sweden, Denmark, Norway and Finland. CONCLUSIONS: According to the analysis, treatment with a moisturizing cream was found to be a cost-effective option compared with no treatment in eczema-free periods in adult patients with AD in the four Nordic countries.

ABSTRACT

Topical corticosteroid therapies are widely utilized, despite the controversial results of corticoid therapy in irritant contact dermatitis as a local inflammatory reaction after repeated or single skin exposure to a chemical substance. Although corticoids may reduce the inflammatory response to the irritant, their antiproliferative effects may reduce skin barrier recovery while allowing further penetration of irritants if exposure continues. This overview reexamines the efficacy of corticosteroids in irritant contact dermatitis therapy, and with the minimal controlled experimental data currently available, notes the need for same-in this common clinical entity.

ABSTRACT

Introduction: Topical corticosteroids, available in an array of vehicles are used to control a variety of inflammatory skin diseases. Patients preferences for different vehicles may affect their willingness to use treatment. We assess corticosteroid vehicle preference and potential impact of topical characteristics on adherence and quality of life in patients with psoriasis.Methods: Subjects with psoriasis were recruited from Wake Forest University Dermatology Clinic. Subjects sampled desoximetasone 0.25% spray, betamethasone valerate 0.1% cream, triamcinolone acetonide 0.1% ointment, fluocinonide 0.05% gel, betamethasone valerate 0.1% lotion, clobetasol propionate 0.05% foam, and fluocinonide 0.05% solution in a predetermined randomized order. Subjects completed a Vehicle Preference Measure, Determinants of Adherence Measure, and a Determinants of Quality of Life Measure.Results: Patients preferences for the various products were highly variable. Regarding Determinants of Adherence, patients perception of absorption of the medication was ranked as 'quite important/extremely important' by 85% of total subjects. A majority of patients rated medication side effects as 'quite important/extremely important' when asked to consider topical characteristics effect on quality of life.Discussion: There was wide variation in patient preference for topical medication vehicles used for treating psoriasis. Several vehicle characteristics were considered important to adherence. Given the marked variation in vehicle preference, topical treatment should be individualized according to patients preferences.

ABSTRACT

BACKGROUND: Recent studies have established the pivotal role of irritants and allergens in development of chronic paronychia and the significant improvement with corticosteroid therapy. OBJECTIVES: The objective of this randomized, unblinded, comparative study was to compare the efficacy of tacrolimus ointment 0.1% vs. betamethasone 17-valerate 0.1% in the treatment of chronic paronychia. METHODS: Forty-five patients with chronic paronychia were randomized 1:1:1 to apply twice daily either betamethasone 17-valerate 0.1% or tacrolimus 0.1% ointment or emollient. Protective measures were counselled to all patients. Treatment duration was 3 weeks and patients were followed for an additional 6 weeks. RESULTS: Eight patients in the betamethasone group were considered as cured, two as improved and four as nonresponders at the end of the treatment period. Thirteen patients in the tacrolimus group were considered as cured and one as improved at the end of the treatment period. Nine patients in the emollient group were considered as stable and six failed to respond. Both betamethasone and tacrolimus groups presented statistically significantly greater cure or improvement rates when compared with the emollient group (P<0.001). CONCLUSIONS: Tacrolimus ointment appears to be a more efficacious agent than betamethasone 17-valerate or placebo for the treatment of chronic paronychia.

ABSTRACT

BACKGROUND: Discoid lupus erythematosus (DLE) is commonly treated with topical agents, the most important of which are glucocorticosteroids. However, prolonged use of these agents, especially on sensitive areas such as the face, may result in side-effects (e.g. atrophy and telangiectases) by altering collagen synthesis. Therefore, alternative treatments are needed for these patients. AIM: To investigate and compare the efficacy of topical pimecrolimus 1% cream and topical betamethasone 17-valerate 0.1% cream on facial lesions of DLE. METHODS: This was a randomized double-blind pilot study, performed in outpatient clinics of two major referral hospitals. Ten patients aged 20-53 years with moderate to severe DLE of the face were randomized into two groups for 8 weeks of treatment and 8 weeks of follow-up after treatment. In this double-blind study, one group applied pimecrolimus 1% cream twice daily and the other group applied betamethasone valerate 0.1% cream twice daily to facial lesions. Efficacy end-points included a combined score based on evaluation of erythema, infiltration and presence of scale. RESULTS: Efficacy end-points showed significant improvement in both groups. A decrease of 86% and 73% in clinical severity scores was obtained for pimecrolimus and betamethasone, respectively (P = 0.043). There was no significant difference between the two groups in terms of efficacy (P = 0.1). No adverse effect was found at the end of the 8-week trial in any of our patients. CONCLUSIONS: The efficacy of pimecrolimus 1% cream is comparable with that of betamethasone valerate 0.1% cream in treating facial DLE.

ABSTRACT

Betamethasone valerate dressings are yet another addition to the already long list of available topical corticosteroids. They provide no marked improvement in efficacy and have the typical profile of adverse effects. In addition, they are not very convenient to use.

ABSTRACT

BACKGROUND: Alopecia areata (AA) is one of the most common causes of localized hair loss. There is no universally proven therapy that induces and sustains remission of hair growth in AA. OBJECTIVE: To compare the efficacy and safety of topical latanoprost, minoxidil and betamethasone valerate on hair growth in patients with AA. PATIENTS AND METHODS: Hundred patients with AA classified into five groups of 20 treated with: Group I, latanoprost 0.1% lotion; Group II, minoxidil 5% lotion; Group III, betamethasone valerate 0.1% solution; Group IV, combination of latanoprost lotion and betamethasone valerate solution and Group V, a vehicle lotion control group. RESULTS: There was a statistically significant improvement in all therapeutic groups when compared with control group and reduction of severity of alopecia tool score of scalp and beard before and after treatment for all therapeutic groups. CONCLUSION: Latanoprost, minoxidil and betamethasone valerate are effective and safe in the treatment of patchy AA. The use of latanoprost added to the therapeutic efficacy of topical betamethasone valerate in the treatment of AA and could be an effective adjunctive topical therapy for AA.

ABSTRACT

BACKGROUND: Chronic eczema such as atopic dermatitis imposes significant socio-econo-psychologic burdens on the affected individuals. In addition to conventional topical treatments, phototherapy is recommended for patients with extensive lesions. Although immunosuppression is believed to explain its primary effectiveness, the underlying mechanisms of phototherapy remain unsolved. Ultraviolet irradiation generates various tryptophan photoproducts including 6-formylindolo[3,2-b]-carbazole (FICZ). FICZ is known to be a potent endogenous agonist for aryl hydrocarbon receptor (AHR); however, the biological role of FICZ in chronic eczema is unknown. OBJECTIVE: To investigate the effect of FICZ on chronic eczema such as atopic dermatitis. METHODS: We stimulated HaCaT cells and normal human epidermal keratinocytes (NHEKs) with or without FICZ and then performed quantitative reverse transcriptase polymerase chain reaction, immunofluorescence, and siRNA treatment. We used the atopic dermatitis-like NC/Nga murine model and treated the mice for 2 weeks with either Vaseline® as a control, FICZ ointment, or betamethasone 17-valerate ointment. The dermatitis score, transepidermal water loss, histology, and expression of skin barrier genes and proteins were evaluated. RESULTS: FICZ significantly upregulated the gene expression of filaggrin in both HaCaT cells and NHEKs in an AHR-dependent manner, but did not affect the gene expression of other barrier-related proteins. In addition, FICZ improved the atopic dermatitis-like skin inflammation, clinical scores, and transepidermal water loss in NC/Nga mice compared with those of control mice. On histology, FICZ significantly reduced the epidermal and dermal thickness as well as the number of mast cells. Topical FICZ also significantly reduced the gene expression of Il22. CONCLUSION: These findings highlight the beneficial role of FICZ-AHR and provide a new strategic basis for developing new drugs for chronic eczema.

ABSTRACT

BACKGROUND: Psoriasis is a Th1/Th17-mediated inflammatory dermatosis treated with topical corticosteroids and vitamin D3 analogs (VD3 As). OBJECTIVE: To compare the effects of a VD3 A maxacalcitol and betamethasone valerate (BV) steroid lotion on topical imiquimod (IMQ)-induced psoriasiform skin inflammation. METHODS: Female BALB/c mice were treated with vehicle, maxacalcitol or BV lotion on the skin for 3 days, and IMQ cream for 6 days. q-PCR, H&E, immunohistochemistry and immunofluorescence studies were performed on skin samples. Additionally, mice were treated with vehicle, maxacalcitol or BV lotion for 3 days and CD4+CD25+ regulatory T cells (Tregs) and CD4+CD25- cells from each group were isolated from lymph nodes. Adoptive transfer of the cells was performed on recipient mice which were treated with IMQ cream for 6 days, and skin samples were obtained for q-PCR and H&E staining. RESULTS: Maxacalcitol and BV were comparable in regards clinical improvement, although maxacalcitol reduced the MHC Class II+ inflammatory cell infiltration more than BV in IMQ skin. While both treatments downregulated IL-17 A, IL-17 F, IL-22, IL-12p40, TNF-α and IL-6 mRNA expression levels, only maxacalcitol downregulated IL-23p19 expression. Significantly increased Foxp3+ cell infiltrations and IL-10 expression were noted in maxacalcitol-treated IMQ skin. Adoptive transfer of Treg cells from maxacalcitol-treated donor mice improved IMQ-induced inflammation clinically and histopathologically more than the recipients of Treg cells from BV-treated donor groups, showing reduced levels of inflammatory cytokines and increased IL-10 expression. CONCLUSION: These results indicate that maxacalcitol reduces psoriasiform skin inflammation by inducing Treg cells as well as downregulating IL-23 and IL-17 production.

ABSTRACT

OBJECTIVE: Evaluate and compare the efficacy, safety, and tolerability of coal tar (10% LCD, liquor carbonis detergens), with betamethasone valerate in the therapy of large plaque-type psoriasis. MATERIAL AND METHOD: Patients with stable, mild to moderate plaque psoriasis at the Department of Medicine, Lerdsin General Hospital, Bangkok, Thailand were randomized for treatment with either coal tar (10% LCD) cream or betamethasone valerate cream (0.1%). All patients entered a 2 week wash-out period followed by the creams being applied twice daily until completion at 6 weeks. The patient severity of psoriasis was assessed using the modified Psoriasis Area and Severity Index (PASI) score at baseline and after 2, 4, and 6 weeks of treatment. RESULT: At the end of the trial, the mean reduction of the PASI score from baseline was 38.39% with the coal tar group and 69.36% with the betamethasone valerate group. The mean percentage of the PASI score reduction was statistically significant in both groups but the betamethasone valerate group was significantly superior to the coal tar group. Both drugs' adverse effects were limited to mild irritation localized to the skin without systemic side effects. The Betamethasone valerate cream was safe, effective, and well-tolerated while the coal tar cream was described as messy, malodorous, and with a tendency to staining clothes. CONCLUSION: The investigator's overall assessment of the treatment response at completion of the trial demonstrated that the betamethasone valerate group achieved significantly greater clearance and marked improvement compared with the coal tar group.
